jFinal写的修改密码的具体实现



登陆者更改自己的密码

其实就分两步，第一验证让他验证oldPassword（旧时密码）对了，才能改密码。

[javascript] view plain copy print?

1. //修改密码  
2. function editPwd(){  
3.     var username=$('#loginname').text();//获取用户名  
4.     //console.log(username);  
5.     var oldPwd=$('#oldPwd').val();//旧密码  
6.     var newPwd=$('#newPwd').val();//新密码  
7.     var checkPwd=$('#checkNewPwd').val();//确认密码  
8.     if((oldPwd ==null ||oldPwd =="")||(newPwd ==null ||newPwd =="")||(checkPwd ==null ||checkPwd =="")){  
9.         layer.alert('密码不能为空！',{  
10.             skin:'layui-layer-molv'//样式类名  
11.             ,closeBtn:0  
12.         });  
13.         return;  
14.     }     
15. //  console.log("old="+oldPwd);  
16. //  console.log("new="+newPwd);  
17. //  console.log("checknew="+checkPwd);  
18.     if(newPwd!=checkPwd){  
19.         layer.alert('两次输入的新密码不一致！',{  
20.             skin:'layui-layer-molv'//样式类名  
21.             ,closeBtn:0  
22.         });  
23.         return;  
24.     }  
25.     var check=checkPassword(checkPwd);//这是一个我写好的方法用来判断密码格式是否正确。  
26.     if(check==false){  
27.         layer.alert('密码格式为6-20可带数字、“_”、“.”的字串',{  
28.             skin:'layui-layer-molv'//样式类名  
29.             ,closeBtn:0  
30.         });  
31.         return;  
32.     }  
33.     var strJSON ={"oldPassword":oldPwd,"password":newPwd,"username":username};  
34.     jQuery.ajax({  
35.         url:"./admin/editPassword",  
36.         type:"POST",  
37.         data:strJSON,  
38.         async:false,  
39.         success:function(obj){  
40.             if(obj.state=="0"){  
41.                 $('#myModal1').modal('hide');  
42.                 layer.alert(obj.msg,{  
43.                     skin:'layui-layer-molv'//样式类名  
44.                         ,closeBtn:0  
45.                 });  
46.             }else{  
47.                 errorInfo(obj);//这里也是一个封装好的方法  
48.             }  
49.         },  
50.         error:function(){  
51.             layer.alert('系统错误',{  
52.                 skin:'layui-layer-molv'//样式类名  
53.                 ,closeBtn:0  
54.             });  
55.         },  
56.         comlete:function(obj){  
57.             if(obj.status==200);  
58.         }  
59.     });  
60. }  

//修改密码function editPwd(){var username=$('#loginname').text();//获取用户名//console.log(username);var oldPwd=$('#oldPwd').val();//旧密码var newPwd=$('#newPwd').val();//新密码var checkPwd=$('#checkNewPwd').val();//确认密码if((oldPwd ==null ||oldPwd =="")||(newPwd ==null ||newPwd =="")||(checkPwd ==null ||checkPwd =="")){layer.alert('密码不能为空！',{skin:'layui-layer-molv'//样式类名,closeBtn:0});return;}//console.log("old="+oldPwd);//console.log("new="+newPwd);//console.log("checknew="+checkPwd);if(newPwd!=checkPwd){layer.alert('两次输入的新密码不一致！',{skin:'layui-layer-molv'//样式类名,closeBtn:0});return;}var check=checkPassword(checkPwd);//这是一个我写好的方法用来判断密码格式是否正确。if(check==false){layer.alert('密码格式为6-20可带数字、“_”、“.”的字串',{skin:'layui-layer-molv'//样式类名,closeBtn:0});return;}var strJSON ={"oldPassword":oldPwd,"password":newPwd,"username":username};jQuery.ajax({url:"./admin/editPassword",type:"POST",data:strJSON,async:false,success:function(obj){if(obj.state=="0"){$('#myModal1').modal('hide');layer.alert(obj.msg,{skin:'layui-layer-molv'//样式类名,closeBtn:0});}else{errorInfo(obj);//这里也是一个封装好的方法}},error:function(){layer.alert('系统错误',{skin:'layui-layer-molv'//样式类名,closeBtn:0});},comlete:function(obj){if(obj.status==200);}});}

errorInfo（）和checkPassword（）

[javascript] view plain copy print?

1. //密码验证   
2. //只能输入6-20可带数字、“_”、“.”的字串   
3. function checkPassword(str) {  
4.    var re = /^([a-zA-Z0-9]|[._]){6,19}$/  
5.    if (re.test(str))   
6.    {  
7.        return true;  
8.    }   
9.    else   
10.    {  
11.        return false;  
12.    }  
13. }  
14.   
15. //用来插入每个需要判断state状态决定是否重新登录的类里面  
16. function errorInfo(obj){  
17.     if(obj.state == "-1") //需要登录  
18.     {  
19.         layer.alert(obj.msg, {  
20.               skin: 'layui-layer-molv' //样式类名  
21.               ,closeBtn: 0  
22.               ,shift: 4 //动画类型  
23.             });  
24.     }  
25.         layer.alert(obj.msg, {  
26.             skin: 'layui-layer-molv' //样式类名  
27.                 ,closeBtn:0  
28.           
29.     });  
30. }  

//密码验证 //只能输入6-20可带数字、“_”、“.”的字串 function checkPassword(str) {   var re = /^([a-zA-Z0-9]|[._]){6,19}$/   if (re.test(str))    {       return true;   }    else    {       return false;   }}//用来插入每个需要判断state状态决定是否重新登录的类里面function errorInfo(obj){if(obj.state == "-1") //需要登录{layer.alert(obj.msg, {    skin: 'layui-layer-molv' //样式类名    ,closeBtn: 0    ,shift: 4 //动画类型  });}layer.alert(obj.msg, {skin: 'layui-layer-molv' //样式类名,closeBtn:0});}
